It is now well established that chemistry in our own galaxy as well as in external galaxies can be complex and well-developed. In particular, molecular emissions can be used to explore the physical conditions  and the likely evolutionary status of near and far away galaxies. In this talk,   I will review recent developments in observational as well as theoretical molecular astrophysics in the context of galactic, nearby and more distant galaxies.

I will show how, even for the most distant galaxies, multi-species multi-transitions molecular emissions can be used as a tool to 'disentangle' the multiple and  spatially unresolved gas components, with particular emphasis on tracing the dense star forming gas within a galaxy.
